A. Example of Block Diagram of UE and 5G Network

FIG. 1 is a block diagram of a wireless communication system to which methods proposed in the disclosure are applicable.

Referring to FIG. 1, a device (AI device) including an AI module is defined as a first communication device (910 of FIG. 1), and a processor 911 can perform detailed AI operation.

A 5G network including another device (AI server) communicating with the AI device is defined as a second communication device (920 of FIG. 1), and a processor 921 can perform detailed AI operations.

For example, the HMD may be used to realize VR, AR or MR. For example, the drone may be a flying object that flies by wireless control signals without a person therein. For example, the VR device may include a device that implements objects or backgrounds of a virtual world. For example, the AR device may include a device that connects and implements objects or background of a virtual world to objects, backgrounds, or the like of a real world.

For example, the public safety device may include an image repeater or an imaging device that can be worn on the body of a user. For example, the MTC device and the IoT device may be devices that do not require direct interference or operation by a person. For example, the MTC device and the IoT device may include a smart meter, a bending machine, a thermometer, a smart bulb, a door lock, various sensors, or the like.

Each Tx/Rx module 925 receives a signal through each antenna 926. Each Tx/Rx module provides RF carriers and information to the Rx processor 923. The processor 921 may be related to the memory 924 that stores program code and data. The memory may be referred to as a computer-readable medium.

B. Signal Transmission/Reception Method in Wireless Communication System

FIG. 2 is a diagram showing an example of a signal transmission/reception method in a wireless communication system.

Referring to FIG. 2, when a UE is powered on or enters a new cell, the UE performs an initial cell search operation such as synchronization with a BS (S201). For this operation, the UE can receive a primary synchronization channel (P-SCH) and a secondary synchronization channel (S-SCH) from the BS to synchronize with the BS and acquire information such as a cell ID. In LTE and NR systems, the P-SCH and S-SCH are respectively called a primary synchronization signal (PSS) and a secondary synchronization signal (SSS). After initial cell search, the UE can acquire broadcast information in the cell by receiving a physical broadcast channel (PBCH) from the BS. Further, the UE can receive a downlink reference signal (DL RS) in the initial cell search step to check a downlink channel state. After initial cell search, the UE can acquire more detailed system information by receiving a physical downlink shared channel (PDSCH) according to a physical downlink control channel (PDCCH) and information included in the PDCCH (S202).

Meanwhile, when the UE initially accesses the BS or has no radio resource for signal transmission, the UE can perform a random access procedure (RACH) for the BS (steps S203 to S206). To this end, the UE can transmit a specific sequence as a preamble through a physical random access channel (PRACH) (S203 and S205) and receive a random access response (RAR) message for the preamble through a PDCCH and a corresponding PDSCH (S204 and S206). In the case of a contention-based RACH, a contention resolution procedure may be additionally performed.

After the UE performs the above-described process, the UE can perform PDCCH/PDSCH reception (S207) and physical uplink shared channel (PUSCH)/physical uplink control channel (PUCCH) transmission (S208) as normal uplink/downlink signal transmission processes. Particularly, the UE receives downlink control information (DCI) through the PDCCH. The UE monitors a set of PDCCH candidates in monitoring occasions set for one or more control element sets (CORESET) on a serving cell according to corresponding search space configurations. A set of PDCCH candidates to be monitored by the UE is defined in terms of search space sets, and a search space set may be a common search space set or a UE-specific search space set. CORESET includes a set of (physical) resource blocks having a duration of one to three OFDM symbols. A network can configure the UE such that the UE has a plurality of CORESETs. The UE monitors PDCCH candidates in one or more search space sets. Here, monitoring means attempting decoding of PDCCH candidate(s) in a search space. When the UE has successfully decoded one of PDCCH candidates in a search space, the UE determines that a PDCCH has been detected from the PDCCH candidate and performs PDSCH reception or PUSCH transmission on the basis of DCI in the detected PDCCH. The PDCCH can be used to schedule DL transmissions over a PDSCH and UL transmissions over a PUSCH. Here, the DCI in the PDCCH includes downlink assignment (i.e., downlink grant (DL grant)) related to a physical downlink shared channel and including at least a modulation and coding format and resource allocation information, or an uplink grant (UL grant) related to a physical uplink shared channel and including a modulation and coding format and resource allocation information.

An initial access (IA) procedure in a 5G communication system will be additionally described with reference to FIG. 2.

The UE can perform cell search, system information acquisition, beam alignment for initial access, and DL measurement on the basis of an SSB. The SSB is interchangeably used with a synchronization signal/physical broadcast channel (SS/PBCH) block.

The SSB includes a PSS, an SSS and a PBCH. The SSB is configured in four consecutive OFDM symbols, and a PSS, a PBCH, an SSS/PBCH or a PBCH is transmitted for each OFDM symbol. Each of the PSS and the SSS includes one OFDM symbol and 127 subcarriers, and the PBCH includes 3 OFDM symbols and 576 subcarriers.

Cell search refers to a process in which a UE acquires time/frequency synchronization of a cell and detects a cell identifier (ID) (e.g., physical layer cell ID (PCI)) of the cell. The PSS is used to detect a cell ID in a cell ID group and the SSS is used to detect a cell ID group. The PBCH is used to detect an SSB (time) index and a half-frame.

There are 336 cell ID groups and there are 3 cell IDs per cell ID group. A total of 1008 cell IDs are present. Information on a cell ID group to which a cell ID of a cell belongs is provided/acquired through an SSS of the cell, and information on the cell ID among 336 cell ID groups is provided/acquired through a PSS.

The SSB is periodically transmitted in accordance with SSB periodicity. A default SSB periodicity assumed by a UE during initial cell search is defined as 20 ms. After cell access, the SSB periodicity can be set to one of {5 ms, 10 ms, 20 ms, 40 ms, 80 ms, 160 ms} by a network (e.g., a BS).

Next, acquisition of system information (SI) will be described.

SI is divided into a master information block (MIB) and a plurality of system information blocks (SIGs). SI other than the MIB may be referred to as remaining minimum system information. The MIB includes information/parameter for monitoring a PDCCH that schedules a PDSCH carrying SIB1 (SystemInformationBlock1) and is transmitted by a BS through a PBCH of an SSB. SIB1 includes information related to availability and scheduling (e.g., transmission periodicity and SI-window size) of the remaining SIBs (hereinafter, SIBx, x is an integer equal to or greater than 2). SiBx is included in an SI message and transmitted over a PDSCH. Each SI message is transmitted within a periodically generated time window (i.e., SI-window).

A random access (RA) procedure in a 5G communication system will be additionally described with reference to FIG. 2.

A random access procedure is used for various purposes. For example, the random access procedure can be used for network initial access, handover, and UE-triggered UL data transmission. A UE can acquire UL synchronization and UL transmission resources through the random access procedure. The random access procedure is classified into a contention-based random access procedure and a contention-free random access procedure. A detailed procedure for the contention-based random access procedure is as follows.

A UE can transmit a random access preamble through a PRACH as Msg1 of a random access procedure in UL. Random access preamble sequences having different two lengths are supported. A long sequence length 839 is applied to subcarrier spacings of 1.25 kHz and 5 kHz and a short sequence length 139 is applied to subcarrier spacings of 15 kHz, 30 kHz, 60 kHz and 120 kHz.

When a BS receives the random access preamble from the UE, the BS transmits a random access response (RAR) message (Msg2) to the UE. A PDCCH that schedules a PDSCH carrying a RAR is CRC masked by a random access (RA) radio network temporary identifier (RNTI) (RA-RNTI) and transmitted. Upon detection of the PDCCH masked by the RA-RNTI, the UE can receive a RAR from the PDSCH scheduled by DCI carried by the PDCCH. The UE checks whether the RAR includes random access response information with respect to the preamble transmitted by the UE, that is, Msg1. Presence or absence of random access information with respect to Msg1 transmitted by the UE can be determined according to presence or absence of a random access preamble ID with respect to the preamble transmitted by the UE. If there is no response to Msg1, the UE can retransmit the RACH preamble less than a predetermined number of times while performing power ramping. The UE calculates PRACH transmission power for preamble retransmission on the basis of most recent pathloss and a power ramping counter.

The UE can perform UL transmission through Msg3 of the random access procedure over a physical uplink shared channel on the basis of the random access response information. Msg3 can include an RRC connection request and a UE ID. The network can transmit Msg4 as a response to Msg3, and Msg4 can be handled as a contention resolution message on DL. The UE can enter an RRC connected state by receiving Msg4.

C. Beam Management (BM) Procedure of 5G Communication System

A BM procedure can be divided into (1) a DL MB procedure using an SSB or a CSI-RS and (2) a UL BM procedure using a sounding reference signal (SRS). In addition, each BM procedure can include Tx beam swiping for determining a Tx beam and Rx beam swiping for determining an Rx beam.

The DL BM procedure using an SSB will be described.

Configuration of a beam report using an SSB is performed when channel state information (CSI)/beam is configured in RRC_CONNECTED.

-   -   A UE receives a CSI-ResourceConfig IE including         CSI-SSB-ResourceSetList for SSB resources used for BM from a BS.         The RRC parameter “csi-SSB-ResourceSetList” represents a list of         SSB resources used for beam management and report in one         resource set. Here, an SSB resource set can be set as {SSBx1,         SSBx2, SSBx3, SSBx4, . . . }. An SSB index can be defined in the         range of 0 to 63.     -   The UE receives the signals on SSB resources from the BS on the         basis of the CSI-SSB-ResourceSetList.     -   When CSI-RS reportConfig with respect to a report on SSBRI and         reference signal received power (RSRP) is set, the UE reports         the best SSBRI and RSRP corresponding thereto to the BS. For         example, when reportQuantity of the CSI-RS reportConfig IE is         set to ‘ssb-Index-RSRP’, the UE reports the best SSBRI and RSRP         corresponding thereto to the BS.

When a CSI-RS resource is configured in the same OFDM symbols as an SSB and ‘QCL-TypeD’ is applicable, the UE can assume that the CSI-RS and the SSB are quasi co-located (QCL) from the viewpoint of ‘QCL-TypeD’. Here, QCL-TypeD may mean that antenna ports are quasi co-located from the viewpoint of a spatial Rx parameter. When the UE receives signals of a plurality of DL antenna ports in a QCL-TypeD relationship, the same Rx beam can be applied.

Next, a DL BM procedure using a CSI-RS will be described.

An Rx beam determination (or refinement) procedure of a UE and a Tx beam swiping procedure of a BS using a CSI-RS will be sequentially described. A repetition parameter is set to ‘ON’ in the Rx beam determination procedure of a UE and set to ‘OFF’ in the Tx beam swiping procedure of a BS.

First, the Rx beam determination procedure of a UE will be described.

-   -   The UE receives an NZP CSI-RS resource set IE including an RRC         parameter with respect to ‘repetition’ from a BS through RRC         signaling. Here, the RRC parameter ‘repetition’ is set to ‘ON’.     -   The UE repeatedly receives signals on resources in a CSI-RS         resource set in which the RRC parameter ‘repetition’ is set to         ‘ON’ in different OFDM symbols through the same Tx beam (or DL         spatial domain transmission filters) of the BS.     -   The UE determines an RX beam thereof.     -   The UE skips a CSI report. That is, the UE can skip a CSI report         when the RRC parameter ‘repetition’ is set to ‘ON’.

Next, the Tx beam determination procedure of a BS will be described.

-   -   A UE receives an NZP CSI-RS resource set IE including an RRC         parameter with respect to ‘repetition’ from the BS through RRC         signaling. Here, the RRC parameter ‘repetition’ is related to         the Tx beam swiping procedure of the BS when set to ‘OFF’.     -   The UE receives signals on resources in a CSI-RS resource set in         which the RRC parameter ‘repetition’ is set to ‘OFF’ in         different DL spatial domain transmission filters of the BS.     -   The UE selects (or determines) a best beam.     -   The UE reports an ID (e.g., CRI) of the selected beam and         related quality information (e.g., RSRP) to the BS. That is,         when a CSI-RS is transmitted for BM, the UE reports a CRI and         RSRP with respect thereto to the BS.

Next, the UL BM procedure using an SRS will be described.

-   -   A UE receives RRC signaling (e.g., SRS-Config IE) including a         (RRC parameter) purpose parameter set to ‘beam management” from         a BS. The SRS-Config IE is used to set SRS transmission. The         SRS-Config IE includes a list of SRS-Resources and a list of         SRS-ResourceSets. Each SRS resource set refers to a set of         SRS-resources.

The UE determines Tx beamforming for SRS resources to be transmitted on the basis of SRS-SpatialRelation Info included in the SRS-Config IE. Here, SRS-SpatialRelation Info is set for each SRS resource and indicates whether the same beamforming as that used for an SSB, a CSI-RS or an SRS will be applied for each SRS resource.

-   -   When SRS-SpatialRelationInfo is set for SRS resources, the same         beamforming as that used for the SSB, CSI-RS or SRS is applied.         However, when SRS-SpatialRelationInfo is not set for SRS         resources, the UE arbitrarily determines Tx beamforming and         transmits an SRS through the determined Tx beamforming.

Next, a beam failure recovery (BFR) procedure will be described.

In a beamformed system, radio link failure (RLF) may frequently occur due to rotation, movement or beamforming blockage of a UE. Accordingly, NR supports BFR in order to prevent frequent occurrence of RLF. BFR is similar to a radio link failure recovery procedure and can be supported when a UE knows new candidate beams. For beam failure detection, a BS configures beam failure detection reference signals for a UE, and the UE declares beam failure when the number of beam failure indications from the physical layer of the UE reaches a threshold set through RRC signaling within a period set through RRC signaling of the BS. After beam failure detection, the UE triggers beam failure recovery by initiating a random access procedure in a PCell and performs beam failure recovery by selecting a suitable beam. (When the BS provides dedicated random access resources for certain beams, these are prioritized by the UE). Completion of the aforementioned random access procedure is regarded as completion of beam failure recovery.

D. URLLC (Ultra-Reliable and Low Latency Communication)

URLLC transmission defined in NR can refer to (1) a relatively low traffic size, (2) a relatively low arrival rate, (3) extremely low latency requirements (e.g., 0.5 and 1 ms), (4) relatively short transmission duration (e.g., 2 OFDM symbols), (5) urgent services/messages, etc. In the case of UL, transmission of traffic of a specific type (e.g., URLLC) needs to be multiplexed with another transmission (e.g., eMBB) scheduled in advance in order to satisfy more stringent latency requirements. In this regard, a method of providing information indicating preemption of specific resources to a UE scheduled in advance and allowing a URLLC UE to use the resources for UL transmission is provided.

NR supports dynamic resource sharing between eMBB and URLLC. eMBB and URLLC services can be scheduled on non-overlapping time/frequency resources, and URLLC transmission can occur in resources scheduled for ongoing eMBB traffic. An eMBB UE may not ascertain whether PDSCH transmission of the corresponding UE has been partially punctured and the UE may not decode a PDSCH due to corrupted coded bits. In view of this, NR provides a preemption indication. The preemption indication may also be referred to as an interrupted transmission indication.

With regard to the preemption indication, a UE receives DownlinkPreemption IE through RRC signaling from a BS. When the UE is provided with DownlinkPreemption IE, the UE is configured with INT-RNTI provided by a parameter int-RNTI in DownlinkPreemption IE for monitoring of a PDCCH that conveys DCI format 2_1. The UE is additionally configured with a corresponding set of positions for fields in DCI format 2_1 according to a set of serving cells and positionInDCI by INT-ConfigurationPerServing Cell including a set of serving cell indexes provided by servingCellID, configured having an information payload size for DCI format 2_1 according to dci-Payloadsize, and configured with indication granularity of time-frequency resources according to timeFrequencySect.

The UE receives DCI format 2_1 from the BS on the basis of the DownlinkPreemption IE.

When the UE detects DCI format 2_1 for a serving cell in a configured set of serving cells, the UE can assume that there is no transmission to the UE in PRBs and symbols indicated by the DCI format 2_1 in a set of PRBs and a set of symbols in a last monitoring period before a monitoring period to which the DCI format 2_1 belongs. For example, the UE assumes that a signal in a time-frequency resource indicated according to preemption is not DL transmission scheduled therefor and decodes data on the basis of signals received in the remaining resource region.

E. mMTC (massive MTC)

mMTC (massive Machine Type Communication) is one of 5G scenarios for supporting a hyper-connection service providing simultaneous communication with a large number of UEs. In this environment, a UE intermittently performs communication with a very low speed and mobility. Accordingly, a main goal of mMTC is operating a UE for a long time at a low cost. With respect to mMTC, 3GPP deals with MTC and NB (NarrowBand)-IoT.

mMTC has features such as repetitive transmission of a PDCCH, a PUCCH, a PDSCH (physical downlink shared channel), a PUSCH, etc., frequency hopping, retuning, and a guard period.

That is, a PUSCH (or a PUCCH (particularly, a long PUCCH) or a PRACH) including specific information and a PDSCH (or a PDCCH) including a response to the specific information are repeatedly transmitted. Repetitive transmission is performed through frequency hopping, and for repetitive transmission, (RF) retuning from a first frequency resource to a second frequency resource is performed in a guard period and the specific information and the response to the specific information can be transmitted/received through a narrowband (e.g., 6 resource blocks (RBs) or 1 RB).

F. Basic Operation of AI Processing Using 5G Communication

FIG. 3 shows an example of basic operations of AI processing in a 5G communication system.

The UE transmits specific information to the 5G network (S1). The 5G network may perform 5G processing related to the specific information (S2). Here, the 5G processing may include AI processing. And the 5G network may transmit response including AI processing result to UE (S3).

G. Applied Operations Between UE and 5G Network in 5G Communication System

Hereinafter, the operation of an autonomous vehicle using 5G communication will be described in more detail with reference to wireless communication technology (BM procedure, URLLC, mMTC, etc.) described in FIGS. 1 and 2.

First, a basic procedure of an applied operation to which a method proposed by the present disclosure which will be described later and eMBB of 5G communication are applied will be described.

As in steps S1 and S3 of FIG. 3, the autonomous vehicle performs an initial access procedure and a random access procedure with the 5G network prior to step S1 of FIG. 3 in order to transmit/receive signals, information and the like to/from the 5G network.

More specifically, the autonomous vehicle performs an initial access procedure with the 5G network on the basis of an SSB in order to acquire DL synchronization and system information. A beam management (BM) procedure and a beam failure recovery procedure may be added in the initial access procedure, and quasi-co-location (QCL) relation may be added in a process in which the autonomous vehicle receives a signal from the 5G network.

In addition, the autonomous vehicle performs a random access procedure with the 5G network for UL synchronization acquisition and/or UL transmission. The 5G network can transmit, to the autonomous vehicle, a UL grant for scheduling transmission of specific information. Accordingly, the autonomous vehicle transmits the specific information to the 5G network on the basis of the UL grant. In addition, the 5G network transmits, to the autonomous vehicle, a DL grant for scheduling transmission of 5G processing results with respect to the specific information. Accordingly, the 5G network can transmit, to the autonomous vehicle, information (or a signal) related to remote control on the basis of the DL grant.

Next, a basic procedure of an applied operation to which a method proposed by the present disclosure which will be described later and URLLC of 5G communication are applied will be described.

As described above, an autonomous vehicle can receive DownlinkPreemption IE from the 5G network after the autonomous vehicle performs an initial access procedure and/or a random access procedure with the 5G network. Then, the autonomous vehicle receives DCI format 2_1 including a preemption indication from the 5G network on the basis of DownlinkPreemption IE. The autonomous vehicle does not perform (or expect or assume) reception of eMBB data in resources (PRBs and/or OFDM symbols) indicated by the preemption indication. Thereafter, when the autonomous vehicle needs to transmit specific information, the autonomous vehicle can receive a UL grant from the 5G network.

Next, a basic procedure of an applied operation to which a method proposed by the present disclosure which will be described later and mMTC of 5G communication are applied will be described.

Description will focus on parts in the steps of FIG. 3 which are changed according to application of mMTC.

In step S1 of FIG. 3, the autonomous vehicle receives a UL grant from the 5G network in order to transmit specific information to the 5G network. Here, the UL grant may include information on the number of repetitions of transmission of the specific information and the specific information may be repeatedly transmitted on the basis of the information on the number of repetitions. That is, the autonomous vehicle transmits the specific information to the 5G network on the basis of the UL grant. Repetitive transmission of the specific information may be performed through frequency hopping, the first transmission of the specific information may be performed in a first frequency resource, and the second transmission of the specific information may be performed in a second frequency resource. The specific information can be transmitted through a narrowband of 6 resource blocks (RBs) or 1 RB.

The above-described 5G communication technology can be combined with methods proposed in the present disclosure which will be described later and applied or can complement the methods proposed in the present disclosure to make technical features of the methods concrete and clear.

Other application programs may be installed within the electronic device 100 at time of manufacturing or shipping, which is typically the case for basic functions of the electronic device 100 (for example, receiving a call, placing a call, receiving a message, sending a message, and the like). It is common for application programs to be stored in the memory 170, installed in the electronic device 100, and executed by the controller 180 to perform an operation (or function) for the electronic device 100.

The controller 180 typically functions to control overall operation of the electronic device 100, in addition to the operations associated with the application programs. The controller 180 may provide or process information or functions appropriate for a user by processing signals, data, information and the like, which are input or output by the various components depicted in FIG. 5, or activating application programs stored in the memory 170.

In addition, operations, control or control methods of mobile terminals may be implemented by executing at least one application program stored in the memory 170.

Referring still to FIG. 5, various components depicted in this figure will now be described in more detail.

Regarding the wireless communication unit 110, the broadcast receiving module 111 is typically configured to receive a broadcast signal and/or broadcast associated information from an external broadcast managing entity via a broadcast channel. The broadcast channel may include a satellite channel, a terrestrial channel, or both. In some embodiments, two or more broadcast receiving modules 111 may be utilized to facilitate simultaneously receiving of two or more broadcast channels, or to support switching among broadcast channels.

The mobile communication module 112 can transmit and/or receive wireless signals to and from one or more network entities. Typical examples of a network entity include a base station, an external mobile terminal, a server, and the like. Such network entities form part of a mobile communication network, which is constructed according to technical standards or communication methods for mobile communications (for example, Global System for Mobile Communication (GSM), Code Division Multi Access (CDMA), CDMA2000 (Code Division Multi Access 2000), EV-DO (Enhanced Voice-Data Optimized or Enhanced Voice-Data Only), Wideband CDMA (WCDMA), High Speed Downlink Packet access (HSDPA), HSUPA (High Speed Uplink Packet Access), Long Term Evolution (LTE), LTE-A (Long Term Evolution-Advanced), and the like).

In some embodiments, when the wireless Internet access is implemented according to, for example, WiBro, HSDPA, HSUPA, GSM, CDMA, WCDMA, LTE, LTE-A and the like, as part of a mobile communication network, the wireless Internet module 113 performs such wireless Internet access. As such, the Internet module 113 may cooperate with, or function as, the mobile communication module 112.

The short-range communication module 114 is configured to facilitate short-range communications.

The short-range communication module 114 in general supports wireless communications between the electronic device 100 and a wireless communication system, communications between the electronic device 100 and another electronic device 100, or communications between the mobile terminal and a network where another electronic device 100 (or an external server) is located, via wireless area networks. One example of the wireless area networks is a wireless personal area networks.

In some embodiments, another mobile terminal (which may be configured similarly to electronic device 100) may be a wearable device, for example, a smart watch, a smart glass or a head mounted display (HMD), which is able to exchange data with the electronic device 100 (or otherwise cooperate with the electronic device 100). The short-range communication module 114 may sense or recognize the wearable device, and permit communication between the wearable device and the electronic device 100. In addition, when the sensed wearable device is a device which is authenticated to communicate with the electronic device 100, the controller 180, for example, may cause transmission of data processed in the electronic device 100 to the wearable device via the short-range communication module 114. Hence, a user of the wearable device may use the data processed in the electronic device 100 on the wearable device. For example, when a call is received in the electronic device 100, the user may answer the call using the wearable device. Also, when a message is received in the electronic device 100, the user can check the received message using the wearable device.

The location information module 115 is generally configured to detect, calculate, derive or otherwise identify a position of the mobile terminal. As an example, the location information module 115 includes a Global Position System (GPS) module, a Wi-Fi module, or both. If desired, the location information module 115 may alternatively or additionally function with any of the other modules of the wireless communication unit 110 to obtain data related to the position of the mobile terminal. As one example, when the mobile terminal uses a GPS module, a position of the mobile terminal may be acquired using a signal sent from a GPS satellite. As another example, when the mobile terminal uses the Wi-Fi module, a position of the mobile terminal can be acquired based on information related to a wireless access point (AP) which transmits or receives a wireless signal to or from the Wi-Fi module.

The input unit 120 may be configured to permit various types of input to the mobile terminal 120. Examples of such input include audio, image, video, data, and user input. Image and video input is often obtained using one or more cameras 121. Such cameras 121 may process image frames of still pictures or video obtained by image sensors in a video or image capture mode. The processed image frames can be displayed on the display unit 151 or stored in memory 170. In some cases, the cameras 121 may be arranged in a matrix configuration to permit a plurality of images having various angles or focal points to be input to the electronic device 100. As another example, the cameras 121 may be located in a stereoscopic arrangement to acquire left and right images for implementing a stereoscopic image.

The microphone 122 is generally implemented to permit audio input to the electronic device 100. The audio input can be processed in various manners according to a function being executed in the electronic device 100. If desired, the microphone 122 may include assorted noise removing algorithms to remove unwanted noise generated in the course of receiving the external audio.

The user input unit 123 is a component that permits input by a user. Such user input may enable the controller 180 to control operation of the electronic device 100. The user input unit 123 may include one or more of a mechanical input element (for example, a key, a button located on a front and/or rear surface or a side surface of the electronic device 100, a dome switch, a jog wheel, a jog switch, and the like), or a touch-sensitive input, among others. As one example, the touch-sensitive input may be a virtual key or a soft key, which is displayed on a touch screen through software processing, or a touch key which is located on the mobile terminal at a location that is other than the touch screen. On the other hand, the virtual key or the visual key may be displayed on the touch screen in various shapes, for example, graphic, text, icon, video, or a combination thereof.

The sensing unit 140 is generally configured to sense one or more of internal information of the mobile terminal, surrounding environment information of the mobile terminal, user information, or the like. The controller 180 generally cooperates with the sending unit 140 to control operation of the electronic device 100 or execute data processing, a function or an operation associated with an application program installed in the mobile terminal based on the sensing provided by the sensing unit 140. The sensing unit 140 may be implemented using any of a variety of sensors, some of which will now be described in more detail.

The proximity sensor 141 may include a sensor to sense presence or absence of an object approaching a surface, or an object located near a surface, by using an electromagnetic field, infrared rays, or the like without a mechanical contact. The proximity sensor 141 may be arranged at an inner region of the mobile terminal covered by the touch screen, or near the touch screen.

The proximity sensor 141, for example, may include any of a transmissive type photoelectric sensor, a direct reflective type photoelectric sensor, a mirror reflective type photoelectric sensor, a high-frequency oscillation proximity sensor, a capacitance type proximity sensor, a magnetic type proximity sensor, an infrared rays proximity sensor, and the like. When the touch screen is implemented as a capacitance type, the proximity sensor 141 can sense proximity of a pointer relative to the touch screen by changes of an electromagnetic field, which is responsive to an approach of an object with conductivity. In this case, the touch screen (touch sensor) may also be categorized as a proximity sensor.

The term “proximity touch” will often be referred to herein to denote the scenario in which a pointer is positioned to be proximate to the touch screen without contacting the touch screen. The term “contact touch” will often be referred to herein to denote the scenario in which a pointer makes physical contact with the touch screen. For the position corresponding to the proximity touch of the pointer relative to the touch screen, such position will correspond to a position where the pointer is perpendicular to the touch screen. The proximity sensor 141 may sense proximity touch, and proximity touch patterns (for example, distance, direction, speed, time, position, moving status, and the like). In general, controller 180 processes data corresponding to proximity touches and proximity touch patterns sensed by the proximity sensor 141, and cause output of visual information on the touch screen. In addition, the controller 180 can control the electronic device 100 to execute different operations or process different data according to whether a touch with respect to a point on the touch screen is either a proximity touch or a contact touch.

A touch sensor can sense a touch applied to the touch screen, such as display unit 151, using any of a variety of touch methods. Examples of such touch methods include a resistive type, a capacitive type, an infrared type, and a magnetic field type, among others.

As one example, the touch sensor may be configured to convert changes of pressure applied to a specific part of the display unit 151, or convert capacitance occurring at a specific part of the display unit 151, into electric input signals. The touch sensor may also be configured to sense not only a touched position and a touched area, but also touch pressure and/or touch capacitance. A touch object is generally used to apply a touch input to the touch sensor. Examples of typical touch objects include a finger, a touch pen, a stylus pen, a pointer, or the like.

When a touch input is sensed by a touch sensor, corresponding signals may be transmitted to a touch controller. The touch controller may process the received signals, and then transmit corresponding data to the controller 180. Accordingly, the controller 180 may sense which region of the display unit 151 has been touched. Here, the touch controller may be a component separate from the controller 180, the controller 180, and combinations thereof.

In some embodiments, the controller 180 may execute the same or different controls according to a type of touch object that touches the touch screen or a touch key provided in addition to the touch screen. Whether to execute the same or different control according to the object which provides a touch input may be decided based on a current operating state of the electronic device 100 or a currently executed application program, for example.

The touch sensor and the proximity sensor may be implemented individually, or in combination, to sense various types of touches. Such touches includes a short (or tap) touch, a long touch, a multi-touch, a drag touch, a flick touch, a pinch-in touch, a pinch-out touch, a swipe touch, a hovering touch, and the like.

If desired, an ultrasonic sensor may be implemented to recognize position information relating to a touch object using ultrasonic waves. The controller 180, for example, may calculate a position of a wave generation source based on information sensed by an illumination sensor and a plurality of ultrasonic sensors. Since light is much faster than ultrasonic waves, the time for which the light reaches the optical sensor is much shorter than the time for which the ultrasonic wave reaches the ultrasonic sensor. The position of the wave generation source may be calculated using this fact. For instance, the position of the wave generation source may be calculated using the time difference from the time that the ultrasonic wave reaches the sensor based on the light as a reference signal.

The camera 121 typically includes at least one a camera sensor (CCD, CMOS etc.), a photo sensor (or image sensors), and a laser sensor.

Implementing the camera 121 with a laser sensor may allow detection of a touch of a physical object with respect to a 3D stereoscopic image. The photo sensor may be laminated on, or overlapped with, the display device. The photo sensor may be configured to scan movement of the physical object in proximity to the touch screen. In more detail, the photo sensor may include photo diodes and transistors at rows and columns to scan content received at the photo sensor using an electrical signal which changes according to the quantity of applied light. Namely, the photo sensor may calculate the coordinates of the physical object according to variation of light to thus obtain position information of the physical object.

The display unit 151 is generally configured to output information processed in the electronic device 100. For example, the display unit 151 may display execution screen information of an application program executing at the electronic device 100 or user interface (UI) and graphic user interface (GUI) information in response to the execution screen information.

In some embodiments, the display unit 151 may be implemented as a stereoscopic display unit for displaying stereoscopic images.

A typical stereoscopic display unit may employ a stereoscopic display scheme such as a stereoscopic scheme (a glass scheme), an auto-stereoscopic scheme (glassless scheme), a projection scheme (holographic scheme), or the like.

The display unit 151 of the mobile terminal according to an embodiment of the present disclosure includes a transparent display, and the display unit 151 will be called a transparent display 151 in description of the structure of the electronic device 100 and description of embodiments.

The audio output module 152 is generally configured to output audio data. Such audio data may be obtained from any of a number of different sources, such that the audio data may be received from the wireless communication unit 110 or may have been stored in the memory 170. The audio data may be output during modes such as a signal reception mode, a call mode, a record mode, a voice recognition mode, a broadcast reception mode, and the like. The audio output module 152 can provide audible output related to a particular function (e.g., a call signal reception sound, a message reception sound, etc.) performed by the electronic device 100. The audio output module 152 may also be implemented as a receiver, a speaker, a buzzer, or the like.

A haptic module 153 can be configured to generate various tactile effects that a user feels, perceive, or otherwise experience. A typical example of a tactile effect generated by the haptic module 153 is vibration. The strength, pattern and the like of the vibration generated by the haptic module 153 can be controlled by user selection or setting by the controller. For example, the haptic module 153 may output different vibrations in a combining manner or a sequential manner.

Besides vibration, the haptic module 153 can generate various other tactile effects, including an effect by stimulation such as a pin arrangement vertically moving to contact skin, a spray force or suction force of air through a jet orifice or a suction opening, a touch to the skin, a contact of an electrode, electrostatic force, an effect by reproducing the sense of cold and warmth using an element that can absorb or generate heat, and the like.

The haptic module 153 can also be implemented to allow the user to feel a tactile effect through a muscle sensation such as the user's fingers or arm, as well as transferring the tactile effect through direct contact. Two or more haptic modules 153 may be provided according to the particular configuration of the electronic device 100.

An optical output module 154 can output a signal for indicating an event generation using light of a light source. Examples of events generated in the electronic device 100 may include message reception, call signal reception, a missed call, an alarm, a schedule notice, an email reception, information reception through an application, and the like.

A signal output by the optical output module 154 may be implemented in such a manner that the mobile terminal emits monochromatic light or light with a plurality of colors. The signal output may be terminated as the mobile terminal senses that a user has checked the generated event, for example.

The interface unit 160 serves as an interface for external devices to be connected with the electronic device 100. For example, the interface unit 160 can receive data transmitted from an external device, receive power to transfer to elements and components within the electronic device 100, or transmit internal data of the electronic device 100 to such external device. The interface unit 160 may include wired or wireless headset ports, external power supply ports, wired or wireless data ports, memory card ports, ports for connecting a device having an identification module, audio input/output (I/O) ports, video I/O ports, earphone ports, or the like.

The identification module may be a chip that stores various information for authenticating authority of using the electronic device 100 and may include a user identity module (UIM), a subscriber identity module (SIM), a universal subscriber identity module (USIM), and the like. In addition, the device having the identification module (also referred to herein as an “identifying device”) may take the form of a smart card. Accordingly, the identifying device can be connected with the terminal 100 via the interface unit 160.

When the electronic device 100 is connected with an external cradle, the interface unit 160 can serve as a passage to allow power from the cradle to be supplied to the electronic device 100 or may serve as a passage to allow various command signals input by the user from the cradle to be transferred to the mobile terminal there through. Various command signals or power input from the cradle may operate as signals for recognizing that the mobile terminal is properly mounted on the cradle.

The memory 170 can store programs to support operations of the controller 180 and store input/output data (for example, phonebook, messages, still images, videos, etc.). The memory 170 may store data related to various patterns of vibrations and audio which are output in response to touch inputs on the touch screen.

The memory 170 may include one or more types of storage mediums including a Flash memory, a hard disk, a solid state disk, a silicon disk, a multimedia card micro type, a card-type memory (e.g., SD or DX memory, etc), a Random Access Memory (RAM), a Static Random Access Memory (SRAM), a Read-Only Memory (ROM), an Electrically Erasable Programmable Read-Only Memory (EEPROM), a Programmable Read-Only memory (PROM), a magnetic memory, a magnetic disk, an optical disk, and the like. The electronic device 100 may also be operated in relation to a network storage device that performs the storage function of the memory 170 over a network, such as the Internet.

The controller 180 may typically control the general operations of the electronic device 100. For example, the controller 180 may set or release a lock state for restricting a user from inputting a control command with respect to applications when a status of the mobile terminal meets a preset condition.

The controller 180 can also perform the controlling and processing associated with voice calls, data communications, video calls, and the like, or perform pattern recognition processing to recognize a handwriting input or a picture drawing input performed on the touch screen as characters or images, respectively. In addition, the controller 180 can control one or a combination of those components in order to implement various exemplary embodiments disclosed herein.

The power supply unit 190 receives external power or provide internal power and supply the appropriate power required for operating respective elements and components included in the electronic device 100. The power supply unit 190 may include a battery, which is typically rechargeable or be detachably coupled to the terminal body for charging.

The power supply unit 190 may include a connection port. The connection port may be configured as one example of the interface unit 160 to which an external charger for supplying power to recharge the battery is electrically connected.

As another example, the power supply unit 190 may be configured to recharge the battery in a wireless manner without use of the connection port. In this example, the power supply unit 190 can receive power, transferred from an external wireless power transmitter, using at least one of an inductive coupling method which is based on magnetic induction or a magnetic resonance coupling method which is based on electromagnetic resonance.

Various embodiments described herein may be implemented in a computer-readable medium, a machine-readable medium, or similar medium using, for example, software, hardware, or any combination thereof.

FIG. 5 is a block diagram of an AI device according to an embodiment of the present disclosure.

An AI device 20 may include an electronic device including an AI module that can perform AI processing, a server including the AI module, or the like. Further, the AI device 20 may be included as at least one component of the vehicle 10 shown in FIG. 2 to perform together at least a portion of the AI processing.

The AI processing may include all operations related to driving of the vehicle 10 shown in FIG. 5. For example, an autonomous vehicle can perform operations of processing/determining, and control signal generating by performing AI processing on sensing data or driver data. Further, for example, an autonomous vehicle can perform autonomous driving control by performing AI processing on data acquired through interaction with other electronic devices included in the vehicle.

The AI device 20 may include an AI processor 21, a memory 25, and/or a communication unit 27.

The AI device 20, which is a computing device that can learn a neural network, may be implemented as various electronic devices such as a server, a desktop PC, a notebook PC, and a tablet PC.

The AI processor 21 can learn a neural network using programs stored in the memory 25. In particular, the AI processor 21 can learn a neural network for recognizing data related to vehicles. Here, the neural network for recognizing data related to vehicles may be designed to simulate the brain structure of human on a computer and may include a plurality of network nodes having weights and simulating the neurons of human neural network. The plurality of network nodes can transmit and receive data in accordance with each connection relationship to simulate the synaptic activity of neurons in which neurons transmit and receive signals through synapses. Here, the neural network may include a deep learning model developed from a neural network model. In the deep learning model, a plurality of network nodes is positioned in different layers and can transmit and receive data in accordance with a convolution connection relationship. The neural network, for example, includes various deep learning techniques such as deep neural networks (DNN), convolutional deep neural networks (CNN), recurrent neural networks (RNN), a restricted boltzmann machine (RBM), deep belief networks (DBN), and a deep Q-network, and can be applied to fields such as computer vision, voice recognition, natural language processing, and voice/signal processing.

Meanwhile, a processor that performs the functions described above may be a general learning unit 24.

The learning data acquiring unit 23 can acquire learning data required for a neural network model for classifying and recognizing data. For example, the learning data acquiring unit 23 can acquire, as learning data, vehicle data and/or sample data to be input to a neural network model.

The model learning unit 24 can perform learning such that a neural network model has a determination reference about how to classify predetermined data, using the acquired learning data. In this case, the model learning unit 24 can train a neural network model through supervised learning that uses at least some of learning data as a determination reference. Alternatively, the model learning data 24 can train a neural network model through unsupervised learning that finds out a determination reference by performing learning by itself using learning data without supervision. Further, the model learning unit 24 can train a neural network model through reinforcement learning using feedback about whether the result of situation determination according to learning is correct. Further, the model learning unit 24 can train a neural network model using a learning algorithm including error back-propagation or gradient decent.

When a neural network model is learned, the model learning unit 24 can store the learned neural network model in the memory. The model learning unit 24 may store the learned neural network model in the memory of a server connected with the AI device 20 through a wire or wireless network.

The data learning unit 22 may further include a learning data preprocessor (not shown) and a learning data selector (not shown) to improve the analysis result of a recognition model or reduce resources or time for generating a recognition model.

The learning data preprocessor can preprocess acquired data such that the acquired data can be used in learning for situation determination. For example, the learning data preprocessor can process acquired data in a predetermined format such that the model learning unit 24 can use learning data acquired for learning for image recognition.

Further, the learning data selector can select data for learning from the learning data acquired by the learning data acquiring unit 23 or the learning data preprocessed by the preprocessor. The selected learning data can be provided to the model learning unit 24. For example, the learning data selector can select only data for objects included in a specific area as learning data by detecting the specific area in an image acquired through a camera of a vehicle.

Further, the data learning unit 22 may further include a model estimator (not shown) to improve the analysis result of a neural network model.

The model estimator inputs estimation data to a neural network model, and when an analysis result output from the estimation data does not satisfy a predetermined reference, it can make the model learning unit 22 perform learning again. In this case, the estimation data may be data defined in advance for estimating a recognition model. For example, when the number or ratio of estimation data with an incorrect analysis result of the analysis result of a recognition model learned with respect to estimation data exceeds a predetermined threshold, the model estimator can estimate that a predetermined reference is not satisfied.

The communication unit 27 can transmit the AI processing result by the AI processor 21 to an external electronic device.

Here, the external electronic device may be defined as an autonomous vehicle. Further, the AI device 20 may be defined as another vehicle or a 5G network that communicates with the autonomous vehicle. Meanwhile, the AI device 20 may be implemented by being functionally embedded in an autonomous module included in a vehicle. Further, the 5G network may include a server or a module that performs control related to autonomous driving.

Meanwhile, the AI device 20 shown in FIG. 5 was functionally separately described into the AI processor 21, the memory 25, the communication unit 27, etc., but it should be noted that the aforementioned components may be integrated in one module and referred to as an AI module.

FIG. 6 shows an example of a DNN model to which the present disclosure is applicable.

A deep neural network (DNN) is an artificial neural network (ANN) with multiple hidden layers between an input layer and an output layer. The deep neural network can model complex non-linear relationships like a typical artificial neural network. The extra layers enable composition of features from lower layers, potentially modeling complex data with fewer units than a similarly performing artificial neural network.

For example, in DNN architectures for object identification models, each object is expressed as a layered composition of image primitives.

The “deep” in “deep learning” refers to the number of layers in the artificial neural network. Deep learning is a machine learning paradigm that uses such a sufficiently deep artificial neural network as a learning model. Also, the sufficiently deep artificial neural network used for deep learning is commonly referred to as a deep neural network (DNN).

In the present disclosure, data sets required to train a POI data creation model may be fed into the input layer of the DNN, and meaningful data that can be used by the user may be created through the output layer as the data sets flow through the hidden layers.

While in the specification of the present disclosure, these artificial neural networks used for this deep learning method are commonly referred to as DNNs, it is needless to say that another deep learning method is applicable as long as meaningful data can be outputted in a way similar to the above deep learning method.

FIG. 7 shows an example of an OCR model to which the present disclosure may be applied.

The OCR model is an automatic recognition technology that converts text and images on printed or captured images into digital data. Examples of using the technology include recognition of text of business cards or handwriting information on papers. The related art OCR model operates as a subdivided module such as a module for finding a text line and a module for splitting letters (i.e., characters). Features that recognize different patterns of these characters must to be designed by a developer. Further, the OCR model limitedly operate only in high quality images.

In recent years, the field of OCR has improved in accuracy by applying deep learning, and it generates rules (feature extraction) that recognizes text in images through massive data learning on its own. The following is an example of an OCR model using the deep learning technology.

According to an embodiment, the controller 180 may perform pre-processing by applying the deep learning-based OCR model (S71).

Computers may recognize pixels having similar brightness values as a chunk, and more easily detect a letter having a color different from the periphery and having a different structure or point of continuity. Thus, a recognition rate may be significantly improved through pre-processing.

An example of such pre-processing is as follows. A low-color image is converted into grayscale. Subsequently, histogram equalization is performed. A sharper image may be obtained by maximizing contrast by redistributing a brightness distribution of the image. However, there is still a limitation in clearly distinguishing between a background and a letter. To solve this problem, binarization is performed. If a pixel value is 255 (white), it is changed to ‘0’, and if it is 0 to 254 (gray and black), it is changed to ‘1’. As a result, the background and the letter may be separated more clearly.

The controller 180 may perform a text detecting operation by applying an OCR model based on deep learning (S72).

After the image is put into the DNN, feature values are obtained. The data to be obtained is a text area (text box) and a rotation angle of the text box. Picking out the text area from the input image may reduce unnecessary computation. Rotation information is used to make the tilted text area horizontal. Thereafter, the image is cut into text units. Through this step, an individual character image or word image may be obtained.

The controller 180 may perform a text recognition operation by applying a deep learning based OCR model (S73).

In order to recognize which letter each image contains, a DNN is used. The DNN learns how to recognize individual words and letters in the form of images. Meanwhile, the types of words or strings that the DNN may recognize vary by languages. Therefore, for general-purpose OCR, a module for estimating language using only images may be necessary.

The controller 180 may perform post-processing by applying an OCR model based on deep learning (S74).

OCR post-processes character recognition errors in a similar way that humans accept text. There are two ways. The first is to use features of each letter. An error is corrected by distinguishing between similar letters (similar pairs) such as “

’, ‘

’, and ‘

’. The second way is to use contextual information. To this end, a language model or a dictionary may be necessary, and a language model that learns numerous text data on the web may be constructed through deep learning.

The present disclosure is to apply an existing deep learning-based OCR model in a more advanced form through federated learning (to be described later).

Text of a business card may be recognized through the camera of the terminal, the above-described deep learning-based OCR model may be used to store the text of the business card. To train the OCR model, a large amount of labeled training data is required. However, even with the OCR model trained with a large amount of data, an error inevitably occurs when new data is input in an actual use environment.

In the training method of the OCR model proposed in the present disclosure, the data generated through an inference error of the model is obtained directly from an edge device, which is an environment in which the actual model is used, and then learned, a result of the learning is transmitted to a model averaging server and merged to create a better OCR model, and thereafter, the model is transmitted to each edge-device.

Hereinafter, the concept of federated learning applied to exemplary embodiments of the present disclosure will be described.

The three main requirement areas in the 5G system are (1) enhanced Mobile Broadband (eMBB) area, (2) massive Machine Type Communication (mMTC) area, and (3) Ultra-Reliable and Low Latency Communication (URLLC) area.

Some use case may require a plurality of areas for optimization, but other use case may focus only one Key Performance Indicator (KPI). The 5G system supports various use cases in a flexible and reliable manner.

eMBB far surpasses the basic mobile Internet access, supports various interactive works, and covers media and entertainment applications in the cloud computing or augmented reality environment. Data is one of core driving elements of the 5G system, which is so abundant that for the first time, the voice-only service may be disappeared. In the 5G, voice is expected to be handled simply by an application program using a data connection provided by the communication system. Primary causes of increased volume of traffic are increase of content size and increase of the number of applications requiring a high data transfer rate. Streaming service (audio and video), interactive video, and mobile Internet connection will be more heavily used as more and more devices are connected to the Internet. These application programs require always-on connectivity to push real-time information and notifications to the user. Cloud-based storage and applications are growing rapidly in the mobile communication platforms, which may be applied to both of business and entertainment uses. And the cloud-based storage is a special use case that drives growth of uplink data transfer rate. The 5G is also used for cloud-based remote works and requires a much shorter end-to-end latency to ensure excellent user experience when a tactile interface is used. Entertainment, for example, cloud-based game and video streaming, is another core element that strengthens the requirement for mobile broadband capability. Entertainment is essential for smartphones and tablets in any place including a high mobility environment such as a train, car, and plane. Another use case is augmented reality for entertainment and information search. Here, augmented reality requires very low latency and instantaneous data transfer.

Also, one of highly expected 5G use cases is the function that connects embedded sensors seamlessly in every possible area, namely the use case based on mMTC. Up to 2020, the number of potential IoT devices is expected to reach 20.4 billion. Industrial IoT is one of key areas where the 5G performs a primary role to maintain infrastructure for smart city, asset tracking, smart utility, agriculture and security.

URLLC includes new services which may transform industry through ultra-reliable/ultra-low latency links, such as remote control of major infrastructure and self-driving cars. The level of reliability and latency are essential for smart grid control, industry automation, robotics, and drone control and coordination.

Next, a plurality of use cases will be described in more detail.

The 5G may complement Fiber-To-The-Home (FTTH) and cable-based broadband (or DOCSIS) as a means to provide a stream estimated to occupy hundreds of megabits per second up to gigabits per second. This fast speed is required not only for virtual reality and augmented reality but also for transferring video with a resolution more than 4K (6K, 8K or more). VR and AR applications almost always include immersive sports games. Specific application programs may require a special network configuration. For example, in the case of VR game, to minimize latency, game service providers may have to integrate a core server with the edge network service of the network operator.

Automobiles are expected to be a new important driving force for the 5G system together with various use cases of mobile communication for vehicles. For example, entertainment for passengers requires high capacity and high mobile broadband at the same time. This is so because users continue to expect a high-quality connection irrespective of their location and moving speed. Another use case in the automotive field is an augmented reality dashboard. The augmented reality dashboard overlays information, which is a perception result of an object in the dark and contains distance to the object and object motion, on what is seen through the front window. In a future, a wireless module enables communication among vehicles, information exchange between a vehicle and supporting infrastructure, and information exchange among a vehicle and other connected devices (for example, devices carried by a pedestrian). A safety system guides alternative courses of driving so that a driver may drive his or her vehicle more safely and to reduce the risk of accident. The next step will be a remotely driven or self-driven vehicle. This step requires highly reliable and highly fast communication between different self-driving vehicles and between a self-driving vehicle and infrastructure. In the future, it is expected that a self-driving vehicle takes care of all of the driving activities while a human driver focuses on dealing with an abnormal driving situation that the self-driving vehicle is unable to recognize. Technical requirements of a self-driving vehicle demand ultra-low latency and ultra-fast reliability up to the level that traffic safety may not be reached by human drivers.

The smart city and smart home, which are regarded as essential to realize a smart society, will be embedded into a high-density wireless sensor network. Distributed networks comprising intelligent sensors may identify conditions for cost-efficient and energy-efficient conditions for maintaining cities and homes. A similar configuration may be applied for each home. Temperature sensors, window and heating controllers, anti-theft alarm devices, and home appliances will be all connected wirelessly. Many of these sensors typified with a low data transfer rate, low power, and low cost. However, for example, real-time HD video may require specific types of devices for the purpose of surveillance.

As consumption and distribution of energy including heat or gas is being highly distributed, automated control of a distributed sensor network is required. A smart grid collects information and interconnect sensors by using digital information and communication technologies so that the distributed sensor network operates according to the collected information. Since the information may include behaviors of energy suppliers and consumers, the smart grid may help improving distribution of fuels such as electricity in terms of efficiency, reliability, economics, production sustainability, and automation. The smart grid may be regarded as a different type of sensor network with a low latency.

The health-care sector has many application programs that may benefit from mobile communication. A communication system may support telemedicine providing a clinical care from a distance. Telemedicine may help reduce barriers to distance and improve access to medical services that are not readily available in remote rural areas. It may also be used to save lives in critical medical and emergency situations. A wireless sensor network based on mobile communication may provide remote monitoring and sensors for parameters such as the heart rate and blood pressure.

Wireless and mobile communication are becoming increasingly important for industrial applications. Cable wiring requires high installation and maintenance costs. Therefore, replacement of cables with reconfigurable wireless links is an attractive opportunity for many industrial applications. However, to exploit the opportunity, the wireless connection is required to function with a latency similar to that in the cable connection, to be reliable and of large capacity, and to be managed in a simple manner. Low latency and very low error probability are new requirements that lead to the introduction of the 5G system.

Logistics and freight tracking are important use cases of mobile communication, which require tracking of an inventory and packages from any place by using location-based information system. The use of logistics and freight tracking typically requires a low data rate but requires large-scale and reliable location information.

The present disclosure to be described below may be implemented by combining or modifying the respective embodiments to satisfy the aforementioned requirements of the 5G system.

In particular, the self-driving vehicle 12 may recognize an occluded area or an area extending over a predetermined distance or objects located across the area by collecting sensor information from external devices or receive recognized information directly from the external devices.

The self-driving vehicle 12 may perform the operations above by using a learning model built on at least one or more artificial neural networks.

<AI+Robot+Autonomous Navigation>

By employing the AI and autonomous navigation technologies, the robot 11 may be implemented as a guide robot, transport robot, cleaning robot, wearable robot, entertainment robot, pet robot, or unmanned flying robot.

The robot 11 employing the AI and autonomous navigation technologies may correspond to a robot itself having an autonomous navigation function or a robot 11 interacting with the self-driving vehicle 12.

The robot 11 having the autonomous navigation function may correspond collectively to the devices which may move autonomously along a given path without control of the user or which may move by determining its path autonomously.

The robot 11 and the self-driving vehicle 12 having the autonomous navigation function may use a common sensing method to determine one or more of the travel path or navigation plan. For example, the robot 11 and the self-driving vehicle 12 having the autonomous navigation function may determine one or more of the travel path or navigation plan by using the information sensed through lidar, radar, and camera.

The robot 11 interacting with the self-driving vehicle 12, which exists separately from the self-driving vehicle 12, may be associated with the autonomous navigation function inside or outside the self-driving vehicle 12 or perform an operation associated with the user riding the self-driving vehicle 12.

At this time, the robot 11 interacting with the self-driving vehicle 12 may obtain sensor information in place of the self-driving vehicle 12 and provide the sensed information to the self-driving vehicle 12; or may control or assist the autonomous navigation function of the self-driving vehicle 12 by obtaining sensor information, generating information of the surroundings or object information, and providing the generated information to the self-driving vehicle 12.

Also, the robot 11 interacting with the self-driving vehicle 12 may control the function of the self-driving vehicle 12 by monitoring the user riding the self-driving vehicle 12 or through interaction with the user. For example, if it is determined that the driver is drowsy, the robot 11 may activate the autonomous navigation function of the self-driving vehicle 12 or assist the control of the driving platform of the self-driving vehicle 12. Here, the function of the self-driving vehicle 12 controlled by the robot 12 may include not only the autonomous navigation function but also the navigation system installed inside the self-driving vehicle 12 or the function provided by the audio system of the self-driving vehicle 12.

Also, the robot 11 interacting with the self-driving vehicle 12 may provide information to the self-driving vehicle 12 or assist functions of the self-driving vehicle 12 from the outside of the self-driving vehicle 12. For example, the robot 11 may provide traffic information including traffic sign information to the self-driving vehicle 12 like a smart traffic light or may automatically connect an electric charger to the charging port by interacting with the self-driving vehicle 12 like an automatic electric charger of the electric vehicle.

<AI+Robot+XR>

The robot 11 employing the XR technology may correspond to a robot which acts as a control/interaction target in the XR image. In this case, the robot 11 may be distinguished from the XR device 13, both of which may operate in conjunction with each other.

If the robot 11, which acts as a control/interaction target in the XR image, obtains sensor information from the sensors including a camera, the robot 11 or XR device 13 may generate an XR image based on the sensor information, and the XR device 13 may output the generated XR image. And the robot 11 may operate based on the control signal received through the XR device 13 or based on the interaction with the user.

For example, the user may check the XR image corresponding to the viewpoint of the robot 11 associated remotely through an external device such as the XR device 13, modify the navigation path of the robot 11 through interaction, control the operation or navigation of the robot 11, or check the information of nearby objects.

<AI+Autonomous Navigation+XR>

By employing the AI and XR technologies, the self-driving vehicle 12 may be implemented as a mobile robot, unmanned ground vehicle, or unmanned aerial vehicle.

The self-driving vehicle 12 employing the XR technology may correspond to a self-driving vehicle having a means for providing XR images or a self-driving vehicle which acts as a control/interaction target in the XR image. In particular, the self-driving vehicle 12 which acts as a control/interaction target in the XR image may be distinguished from the XR device 13, both of which may operate in conjunction with each other.

The self-driving vehicle 12 having a means for providing XR images may obtain sensor information from sensors including a camera and output XR images generated based on the sensor information obtained. For example, by displaying an XR image through HUD, the self-driving vehicle 12 may provide XR images corresponding to physical objects or image objects to the passenger.

At this time, if an XR object is output on the HUD, at least part of the XR object may be output so as to be overlapped with the physical object at which the passenger gazes. On the other hand, if an XR object is output on a display installed inside the self-driving vehicle 12, at least part of the XR object may be output so as to be overlapped with an image object. For example, the self-driving vehicle 12 may output XR objects corresponding to the objects such as roads, other vehicles, traffic lights, traffic signs, bicycles, pedestrians, and buildings.

If the self-driving vehicle 12, which acts as a control/interaction target in the XR image, obtains sensor information from the sensors including a camera, the self-driving vehicle 12 or XR device 13 may generate an XR image based on the sensor information, and the XR device 13 may output the generated XR image. And the self-driving vehicle 12 may operate based on the control signal received through an external device such as the XR device 13 or based on the interaction with the user.

[Extended Reality Technology]

eXtended Reality (XR) refers to all of Virtual Reality (VR), Augmented Reality (AR), and Mixed Reality (MR). The VR technology provides objects or backgrounds of the real world only in the form of CG images, AR technology provides virtual CG images overlaid on the physical object images, and MR technology employs computer graphics technology to mix and merge virtual objects with the real world.

MR technology is similar to AR technology in a sense that physical objects are displayed together with virtual objects. However, while virtual objects supplement physical objects in the AR, virtual and physical objects co-exist as equivalents in the MR.

The XR technology may be applied to Head-Mounted Display (HMD), Head-Up Display (HUD), mobile phone, tablet PC, laptop computer, desktop computer, TV, digital signage, and so on, where a device employing the XR technology may be called an XR device.

The collection engine 901 may collect source data related to user information through the terminal of the user. The source data may be classified into categories defined to recommend an appropriate service for the user and managed in corresponding databases (DB). Such DB may be included in a home appliance, a virtual reality (VR) device, a mobile phone, a robot, etc., and may be managed by a separate server.

The classification engine 902 may perform classification by clustering source data acquired from the collection engine 901. Clustering refers to grouping similar entities, whereby clusters to be provided to the service provider 903 may be generated. To this end, artificial intelligence (AI) technology may be used, and the clusters may be managed in the form of big data. In addition, using the generated clusters, the classification engine 902 may generate a profile of the user, which can be used to recommend a service at the service provider 903.

The service provider 903 may recommend an appropriate service for the user by use of the user's profile generated by the classification engine 902. To this end, an AI technology may be used, and a terminal or the like may be connected to a different service provider via a network to thereby request a service of recommendation, and the service provider 903 may recommend or advertise an appropriate service to the user through the terminal or the like.

Unlike an existing service providing method, the aforementioned intelligence service model may directly analyze a service necessary for the user even without the user's request and may select and provide the necessary service to the user.

FIG. 10 is an example of structure of an intelligence service model to which the present disclosure can be applied.

The collection engine 901 may collect source data through the user's terminal or the like (S1010). Such source data may include the user's location information, message information, images/videos, calendar information, information on a “to-do-list” input by the user, call record, memo, application usage record, etc. As descried above, such information may be managed in a corresponding DB.

The classification engine 902 may cluster source data collected by the collection engine 901 by defined categories (S1020). Using the generated clusters, the classification engine 902 may generate the user's profile which is to be provided to the service provider 903.

The service provider 903 may recommend an appropriate service for the user by use of the user's profile generated by the classification engine 902 (S1030). To this end, the user's profile may be generated in order to determine the following user information. For example, the user's profile may be classified as data used to determine whether the user has a child, whether the user is married, whether the user has a pet, a primary means of transportation, whether the user is a student or an employee, a frequently used mart or brand, gender, etc., and then the classified profile may be provided to the service provider 903.

Using the user's profile, the service provider 903 may request services recommendable to the user from the service provider (S1040).

The present disclosure may provide a method and a device for deriving a sophisticated profile by processing/analyzing source data of a user. The intelligence service model may use the user's profile to thereby provide a customized recommended service to the user improve a retrieving function.

In addition, the present disclosure may derive the user's profile using source data in the terminal without additional information input by the user, and provide recommendable services necessary for the user based on the user's profile.

FIG. 11 is an embodiment to which the present disclosure can be applied.

The collection engine 901 acquires source data for generating a profile of a user through the terminal of the user or the like (S1110). The source data may refer to big data that can be generated by the user by use of the terminal or the like.

Using the source data, the classification engine 902 generates a cluster comprised of a set of data having categories of services recommendable to the user in order to generate the profile of the user (S1120). In order to generate the cluster, information on the services recommendable to the user may be acquired by a service or the like managed by an external corporate which provides the corresponding service.

In addition, the classification engine 902 generates the user's profile by analyzing the cluster (S1130). The user's profile may refer to the user's private information that is necessary for an external service in order to recommend a service to the user through a server or the like which is managed by an external corporate which provides the corresponding service.

The terminal or the like transmits the user's profile to the service provider 903 (S1140). Here, the service provider 903 may refer to an external corporate that can recommend an appropriate service to the user based on the user's profile, and the external corporate may specify the profile of the user using log-in information of the user and transceiver data with the terminal or the like through an application or the like.

The service provider 903 may recommend an appropriate service for the user based on the user's profile (S1150). The user may be provided with a service recommended by the service provider 903 through the terminal or the like or may acquire information on the recommended service.

FIG. 12 is a diagram for explaining how to profile a user by a method for controlling an intelligent device according to an embodiment of the present disclosure. The method shown in FIG. 12 may be performed by the processor shown in FIG. 4 through an intelligence service model.

To this end, the processor 180 may analyze a usage record of an application in a user terminal through an intelligence service model, and analyze a keyword using text information in the user terminal.

The processor 180 analyzes a name and a category of an application installed in the user terminal (S1210). The name and the category of the application may be acquired through information on the application itself or may be acquired by collecting information on an application purchased or installed by the user through an application provider.

For example, when the name of the application includes a kid-related word such as “kids” and “homework book”, the application may be classified as an application indicating that the user has a child. Alternatively, the category of the application is classified as “kids/education” or “parenting/family”, the application may be classified as an application indicating that the user has a child.

The processor 180 may generate a score representing whether the user has a child (S1220) by analyzing a usage time of the application indicating that the user has a child.

For example, the recent 30-day usage record of the application indicating that the user has a child may be analyzed, and the score may be calculated as in Equation as below.

$\begin{matrix} {{Score} = \frac{\left( {{launchCount}*{usageTime}} \right)}{\left( {{launchCount} + {usageTime}} \right)}} & \left\lbrack {{Equation}\mspace{14mu} 1} \right\rbrack \end{matrix}$

The processor 180 may combine kids-related keywords, determine whether the combination of the keywords matches text information in a message DB or a contact DB of the user terminal or the like, and determine, based on a result of the determination, whether the user has a child (S1230).

For example, the processor 180 may set a name registered in a contact list of the user terminal or the like, a kid-related word/brand keyword, and a kid-related negative word in the intelligence model. Using a combination of such keywords, the intelligence model may determine, through the classification engine 902, whether the combination of the keywords exists in text information of source data acquired through the collection engine 901. When the combination of the keywords exists in the text information, a score used to determine whether the user has a child may be generated.

To this end, deep learning and AI technologies may be used, and the above-described keywords and text information may be used as an input value.

Based on the score generated by the above-described operation, the processor 180 may determine whether the user has a child (S1240).

The above-described operations may be performed at the same time and are not limited to the above-described order by which the operations are performed.

FIG. 13 is a diagram for explaining another example of performing user profiling by a method for controlling an intelligent device according to an embodiment of the present disclosure. The method shown in FIG. 13 may be performed by the processor shown in FIG. 4 through an intelligence service model.

Referring to FIG. 13(a), in order to determine whether the user is married, the processor 180 may use the intelligence service model and may use a marriage-related keyword, contact information, and a result of the aforementioned determination as to whether the user has a child. The marriage-related keyword may be classified as male or female. For example, a male marriage-related keyword may include Jang-in-uh-roon, Jang-mo-nim, Chuh-hyung, Chuh-je, Chuh-nam, etc., and a female marriage-related keyword may include Shiabeonim, Shieomeonim, ajubeoni, Do-ryeon-nim, etc.

Referring to FIG. 13(b), the processor 180 may first determine whether the user has a child (S1310) in order to determine whether the user is married

When it is determined that the user has no child, the processor 180 may determine whether there is contact information having a marriage-related keyword in a contact of the user's terminal (s1320). When there is no contact information having a marriage-related keyword, the processor 180 may determine that the user is a single man or a single woman.

When it is determined that the user has a child or when there is contact information having a marriage-related keyword even though it is determined that the user has no child, the processor 180 may determine whether there is contact information having a male marriage-related keyword (S1330).

When there is a male marriage-related keyword, the processor 180 may determine that the user is a married man, and, when there is no male marriage-related keyword, the processor 180 may determine that the user is a married woman.

FIG. 14 is a diagram for explaining another example for performing user profiling by a method for controlling an intelligent device according to an embodiment of the present disclosure. The method shown in FIG. 14 may be performed by the processor shown in FIG. 4 through an intelligence service model. The processor 180 may determine whether the user has a pet by using Media DB which manages data related to images acquired by the user's terminal or the like through the intelligence service model.

The processor 180 may set a Tag list to determine whether a pet-related Tag is included in a name filed of the Media DB in the intelligence service model (S1400). The Tag list may include names indicating pets and the like. For example, the Tag list may include cat, dalmatian dog, english bulldog, golden retriever, hamster, kitten, pomeranian, poodle, pug, puppy, rabbit, Pet, etc.

In addition, in order to determine time when an image is generated through the Media DB, the processor 180 may acquire information on the time when the corresponding image is generated. A name field and A time field of the Media DB may include a corresponding Tag through the classification engine 902, and a cluster including a set of data in the Media DB, the data which have been generated for the last one month, is generated (S1410).

Based on the cluster, the processor 180 determines whether the corresponding image is generated by a terminal possessed by the user (S1420).

When the corresponding image is generated by the terminal possessed by the user, the processor 180 determines, based on GPS information of corresponding data, whether the corresponding image is generated at the user's home (S1430). For example, based on location information of the user's home, if the corresponding image is generated within 500 meter from the user's home, the processor 180 may determine that the corresponding image is generated at the user's home.

When the number of data satisfying the above requirements is equal to or greater than a predetermined value, the processor 180 may determine that the user has a pet (S1440). For example, when the number of counters exceeds 5, the processor 180 may determine that the user has a pet.

FIG. 15 is a diagram for explaining another example of performing user profiling by a method for controlling an intelligent device according to an embodiment of the present disclosure. The method shown in FIG. 15 may be performed by the processor shown in FIG. 4 through an intelligence service model. The processor 180 may determine the most frequently used means of transportation of the user based on DB related to Bluetooth usage of the user.

In order for the user to determine a type of a device being connected through Bluetooth, the processor 180 sets BluetoothClass.Device through a typeid field of Bluetooth_DB (S1500).

The classification engine 902 acquires, through a time field, usage record of Bluetooth that has been commenced for a predetermined period (e.g., the recent three weeks), compares the usage record of the Bluetooth by use of set BluetoothClass.Device, and generates a cluster including Bluetooth usage record information indicating a device to which the Bluetooth is connected (S1510)

The processor 180 determines whether data in the generated cluster includes data indicating that a type of a Bluetooth-connected device is a car audio (S1520). If there is no data indicating that a type of a Bluetooth-connected device is a car audio, the processor 180 may determine that public transportation is the most frequently used means of transportation for the user.

If there is data indicating a type of a Bluetooth-connected device is a car audio, the processor 180 may determine whether the user walks for a predetermined time, e.g., 15 minutes, or more while commuting (S1530).

If the user walks for the predetermined time or more while commuting, the user may be determined as a public transportation user who has his/her own car. If the user walks in less than the predetermined time, the user may be determined a user who uses his/her car while commuting. A walk time while commuting may be acquired by an AI technology that utilizes the user's input, a health-related application, or source data.

FIGS. 16A and 16B are diagrams for explaining another example of performing user profiling by a method for controlling an intelligent device according to an embodiment of the present disclosure. The method shown in FIGS. 16A and 16B may be performed by the processor shown in FIG. 14 through an intelligence service model. Referring to FIG. 16A, the processor may set a salary-related reference word in the intelligence service model (S1610).

The reference word may include a text whereby identification of a user or owner regarding a terminal or the like can be classified. Such a text may refer to an occupation of the user or owner. For example, the reference word may refer to a word on the basis of which the user can be classified as a university student, an employee, a housewife, or the like.

In addition, in order to determine whether a salary-related word is included in test information such as text messages, the processor 180 may set a salary-related word list in the intelligence model. For example, the salary-related word list may include salary, bonus, pension, incentives, and the like.

Based on data tranceived through a user terminal for a predetermined period, the processor 180 may extract input data to be applied to the intelligence service model (S1620).

For example, the intelligence service model may extract a text messages including “deposition” from text information of text messages which have been received by the user terminal or the like for the last six months (S1630).

The processor 180 may determine whether any word included in the salary-related word list is included in the text message including “deposition, in the tranceived text record (S1630).

When any word included in the salary-related list is included, the processor 180 may determine, on the basis of an application-related DB of a user terminal or the like, whether an application used by employees is installed and used (S1640). When an application used by employees is installed and used, the processor 180 may determine that the user is an employee.

In addition, when an application used by employees is not installed and used, the processor 180 may determine that the user is a freelancer.

When any word included in the salary-related word list is not included in the text message including “deposition”, the processor 180 may determine, on the basis of an application-related DB of a user terminal or the like, whether any application used by university students is installed and used (S1650). In addition, when any application used by university students is installed and used, the processor 180 may determine that the user is a university student, and, when any application used by university students is not installed and used, the processor 180 may determine that the user is a freelancer.

To this end, information on applications used by employees or university students may be provided through the user's input or from an application provider or an external server.

Referring to FIG. 16B, a salary-related word list may be included as an example of a reference word to be set in an intelligence service model. The salary-related word list may include words related to an employee's salary, such as bonus, pension, incentives, pay, bonus, and the like, and this is merely an example and should not be construed as limiting the present disclosure. In addition, referring to FIG. 16B, the processor 180 may extract input data, which is to be applied to the intelligence service model, from a text message transceived record of the user's terminal

FIGS. 17A and 17B are diagrams for explaining another example of performing user profiling by a method for controlling an intelligent device according to an embodiment of the present disclosure. The method shown in FIGS. 17A and 17B may be performed by the processor 180 shown in FIG. 4 through an intelligence service model. An attribute of the user profiling may be about a shopping place of interest for the user. The shopping place of interest for the user may relate to a type or brand of a mart most frequently visited by the user.

Referring to FIGS. 17A and 17B, the processor 180 may set a reference word in the intelligence model (S1700). In the intelligence service model, a mart type list may be set in order to determine a type or brand of the mart most frequently visited by the user. For example, such a list may be classified into categories of supermarket, department store, and convenient store (see FIG. 17B).

The processor 180 may classify a transaction record in data transceived through a user terminal, and extract a payment place from the transaction record (S1710).

For example, the processor 180 acquires a payment place from the recent payment text message and payment information of a Pay application. Preferably, the processor 180 may acquire a payment place from text messages and payment information of the Pay application, which have been accumulated for the last six months.

The processor 180 may determine whether the payment place acquired on the basis of the reference word set in the intelligence service model is a supermarket, a department store, or a convenience store.

The processor 180 may determine whether there are a predetermined number of more places having the same name (S1720). For example, when the number of multiple places having the same name exceeds 5, the processor 180 may determine that a mart type or brand corresponding to the name is a type or brand of a mart frequently visited by the user.

FIG. 18 is a diagram for explaining another example of performing user profiling by a method for controlling an intelligent device according to an embodiment of the present disclosure. The method shown in FIG. 18 may be performed by the processor shown in FIG. 4 through an intelligence service model. An attribute of the user profiling may be to determine gender of a user. According to an embodiment of the present disclosure, the processor 180 may extract voice data of the user by use of the intelligence service model (S1800).

More specifically, the processor 180 may acquire a voice file of the user to trigger Voice Assistant, provided by a user terminal or the like, through the intelligence service model and may extract voice data of the user from the acquired voice file of the user. Alternatively, the intelligence service model may extract voice data of the user during a phone call.

In addition, the processor 180 may acquire contact information in order to analyze a keyword of a name stored in the contact information (S1810).

The processor 180 may apply a deep learning model by use of the voice data and the contact information as an input value in order to analyze gender of the user (S1820).

The processor 180 may generate a cluster including the voice data and the contact information of the user (S1830)

According to an embodiment of the present disclosure, a data cluster may be generated through the classification engine 902 shown in FIG. 9, and a cluster including the acquired voice data and the contact information may be generated.

In a generated cluster, a first weight W1 may be assigned to a result value of voice data analyzed through a machine learning model (e.g., CNN, DNN, etc.) and a second weight W2 may be assigned to a result value of a keyword analyzed through the contact information.

The processor 180 may classify gender of the user by using such weights through a trained machine learning model (S1840).

FIG. 19 is an embodiment to which the present disclosure can be applied.

An intelligence service model may generate a user's profile based on the user's home appliance connection information, car connection information, device connection information, or the like.
